1.2 Warnings regarding the use of batteries
1. WARNING – RISK OF EXPLOSIVE GASES
i. WORKING IN VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS. BATTERIES
GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY OPERATION. FOR
THIS REASON, IT IS OF UTMOST IMPORTANCE THAT EACH TIME BEFORE
SERVICING THE COMBIMASTER INVERTER/CHARGER IN THE VICINITY OF THE
BATTERY, YOU READ THIS MANUAL AND FOLLOW THE INSTRUCTIONS
EXACTLY.
ii. To reduce risk of battery explosion, follow these instructions and those published by
battery manufacturer and manufacturer of any unit you intend to use in vicinity of
battery. Review cautionary marking on these products and on engine.
2. PERSONAL PRECAUTIONS
i. Someone should be within range of your voice or close enough to come to your aid
when you work near a lead-acid battery.
ii. Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing,
or eyes.
iii. Wear complete eye protection and clothing protection. Avoid touching eyes while
working near battery.
iv. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid
enters eye, immediately flood eye with running cold water for at least 10 min and get
medical attention immediately.
v. NEVER smoke or allow a spark or flame in vicinity of battery or engine.
vi. Do not short circuit battery! Be extra cautious to reduce risk of dropping a metal tool
onto battery. It might spark or short-circuit battery or other electrical part that may cause
explosion.
vii. Remove personal metal items such as rings, bracelets, necklaces, and watches when
working with a lead-acid battery. A lead-acid battery can produce a short-circuit current
high enough to weld a ring or the like to metal, causing a severe burn.
viii. NEVER charge a frozen battery.
ix. If necessary to remove battery from a vessel or vehicle, always remove grounded
terminal from battery first. Make sure all accessories in the vessels or vehicle are off, so
as not to cause an arc.
x. Be sure that the area around battery is well ventilated.
xi. Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
xii. Study all battery manufacturer’s specific precautions such as removing or not removing
cell caps while charging and recommended rates of charge.
xiii. Add distilled water in each cell until battery acid reaches level specified by battery
manufacturer. This helps purge excessive gas from cells. Do not overfill. For a battery
without cell caps (e.g. AGM, Gel or Li-ion batteries), carefully follow manufacturer’s
recharging instructions.
xiv. A battery is heavy! It may become a projectile if it is involved in an accident! Ensure
adequate and secure mounting and always use suitable handling equipment for
transportation.
